Product SalesFor Q1 2017, Product sales were $82.0 million, an increase of 29% as compared to 2016.

Contract ManufacturingFor Q1 2017, revenue from the Company’s contract manufacturing operations was $17.6 million, an increase of 132% as compared to 2016. The increase primarily reflects an increase in fill/finish services at the Company’s Camden facility in Baltimore, along with manufacturing of Aptevo Therapeutics Inc. products.

Contracts and GrantsFor Q1 2017, contracts and grants revenue was $17.3 million, a decrease of 45% as compared to 2016. The decrease primarily reflects a reduction in development funding due to the timing of development activities under ongoing programs, as well as a reduction for various programs that were concluded prior to the start of the 2017 period but were funded and ongoing in the prior comparative period in 2016.

Operating Expenses

Cost of Product Sales and Contract ManufacturingFor Q1 2017, Cost of product sales and contract manufacturing was $46.3 million, an increase of 93% as compared to 2016. The increase primarily reflects higher costs associated with the increase in both Other product sales and contract manufacturing.

Research and DevelopmentFor Q1 2017, gross R&D expenses were $20.5 million, a decrease of 22% as compared to 2016. For Q1 2017, net R&D was $3.2 million, as compared to being fully funded and resulting in a net contribution from funded development programs of $5.5 million in 2016. Net R&D, which is more representative of the Company’s actual out-of-pocket investment in product development, is calculated as gross research and development expenses less contracts and grants revenue.

Selling, General and AdministrativeFor Q1 2017, selling, general and administrative expenses were $35.2 million, an increase of 11% as compared to 2016. The increase is attributable to costs associated with restructuring activities within the general and administrative functional groups, and increased costs associated with professional services to support the Company’s strategic growth initiatives.

For Q1 2017 and 2016, net income per diluted share is computed using the “if-converted” method. This method requires net income to be adjusted to add back interest expense and amortization of debt issuance cost, both net of tax, associated with the Company’s 2.875% Convertible Senior Notes due 2021. The following table details the adjustments made in this calculation.

RECONCILIATION OF NET INCOME TO ADJUSTED NET INCOME AND EBITDA

This press release contains two financial measures (Adjusted Net Income and EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization)) that are considered “non-GAAP” financial measures under applicable Securities and Exchange Commission rules and regulations. These non-GAAP financial measures should be considered supplemental to and not a substitute for financial information prepared in accordance with generally accepted accounting principles. The Company’s definition of these non-GAAP measures may differ from similarly titled measures used by others. Adjusted Net Income adjusts for specified items that can be highly variable or difficult to predict, or reflect the non-cash impact of charges resulting from purchase accounting. EBITDA reflects net income excluding the impact of depreciation, amortization, interest expense and provision for income taxes. The Company views these non-GAAP financial measures as a means to facilitate management’s financial and operational decision-making, including evaluation of the Company’s historical operating results and comparison to competitors’ operating results. These non-GAAP financial measures reflect an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results and the reconciliations to the corresponding GAAP financial measure, may provide a more complete understanding of factors and trends affecting the Company’s business.

The determination of the amounts that are excluded from these non-GAAP financial measures are a matter of management judgment and depend upon, among other factors, the nature of the underlying expense or income amounts. Because non-GAAP financial measures exclude the effect of items that will increase or decrease the Company’s reported results of operations, management strongly encourages investors to review the Company’s consolidated financial statements and publicly filed reports in their entirety.
